ATOMIZER FOR HYDROCARBONS.

To all whomt't may concern:

Be it known that I, WILLIAM W. THOMAS, of Jersey City, in the county ofHudson and State of New Jersey, have invented certain 5 new and usefulImprovements in Atomizers for Hydrocarbons, of which the following is aspecication.

My invention relates to atomizcrs for injecting tar and othercombustible liquids into fur- Io naces, and which comprise aliquid-chamber, a.

steam-chamber, outer and inner nozzle-tubes, leading respectively fromthe liquid-chamber andv steam-chamber, and the latter of which carries avalve fitting to a seat in rear of the r 5 former and is movable axiallyfor openin g and closing said valve.

The object of my invention is to effect the more complete atomization orspraying of the hydrocarbonliquid and the more thorough comzo minglingthereof with the steam.

The invention consists in the combination, in an atomizer, with steamand liquid chambers and a nozzle-tube leading from the liquidchamber, ofa steam-tube carrying a valve tting a seat at rear of said nozzle-tubeand extended beyond said valve so as to form between the two tubes achannel of annular transverse section, through which theliquidis sucked,and

over the surfaces of which the liquid to be atomized is distributed. Inorder to more effectively break the hydrocarbon liquid into spray theinterior of the liquid-nozzle tube, beyond the end of the steam-tube,preferably has a sharpedged contraction leaving au opening only a triflelarger than the internal diameter of the steam-tube.

In the accompanying drawings, Figure l represents a longitudinal sectionthrough an apparatus embodying my invention; and Fig. 2

4o represents a transverse section on the line w,

Fig. l. K Similar letters of reference designate corresponding parts inboth iigures.

In the metallic shell or body A of the atomizer are formed two chambers,B C, the first of which is supplied with steam through an inletopening,B', and the second with hydrocarbon liquid through an inlet-opening, C.h

In the liquid-chamber C is inserted a nozzle- 5o tube, D, through whichliquid is discharged from said chamber; and E designates a steamtubeconcentric with the tube D and extending through both the chambers B andC. The tube E passes through a stuffing-box, a, between the twochambers, which preven-ts leakage of steam from the chamber B into thechamber C, and said tube, or a solid rod or stem forming al continuationthereof, passes through a stuffing-box, F, in the end of theatomizer,aud is provided with a handle or hand-Wheel, G. The steam enters thetube E through transverse openings, b, in the side thereof, and thencepasses into the nozzle-tube D. The inner end of the nozzle D forms avalve-seat, to which is fitted a valve, H, carried by the tube E, andthe said tube may be adjusted to open the valve to any required degree.

Ordinarily in atomizers the steam-tube does not extend beyond the valvewhich controls the escape of liquid; but in my atomizer said tube has acontinuation, E', extending some 'distance beyond the valve H andforming between it and the inner surface of the tube D a channelorchamber, I, ot annular transverse section. Beyond the end of the tubeE the tube D is internally contracted or has an annular contraction, c,which has a sharp edge, and forms an openin g very slightly larger thanthe internal diameter of the tube E'.

The hydrocarbon-liquid chamber C, is full of liquid at all times, andwhen the atomizer is to be set in operation the tube E is moved outwardenough to slightly open said valve. The discharge of steam through thesteamtube E then taking place produces a vacuum in the annular space Iand the liquid. which passes the slightly-open .valve in a thin hn,spreads over the interior surface of the tube D and the exterior ot thetube E', and as it reaches the sharp edge of the contraction c isexposed to the action of the current of steam and thoroughly sprayed andmingled therewith.

` What I claim as my invention, and desire to secure by Letters Patent,is- 95 l. In an atomizer, the combination, with steam and liquidchambers and a nozzle-tube extending from the liquid-chamber, of asteamtube carrying a valve litting to a seat at the rear of saidnozzle-tube audextended beyond the roo valve, so as to form between thetwo tubes in valve H, and having the extension E', all subfront of thevalve :L channel of annular transstantialiy k21s specied. verse section,substantially as and for the pnr'- pose specied WILLIAM W.
